Model torque and thrust force in drilling. A theoretical model to predict thrust force and torque in drilling is presented. The method consists of determining the continuous distributions of thrust and torque along the lip and the chisel edge of a twist drill. The calculation uses the oblique cutting model for the lip and the orthogonal cutting model for the chisel edge. Thrust and torque are obtained in terms of the geometric features of the drill, the cutting conditions and the properties of the machined material.

Model momentu i siły w procesie wiercenia. W artykule przedstawiono teoretyczny model do przewidywania siły skrawania i moment przy wierceniu. Metoda polega na wyznaczeniu rozkładu siły i momentu wzdłuż krawędzi wiertła. Do obliczeń zastosowano model ortogonalnego skrawania. Siłę i moment uzyskuje się w zależności od cech geometrycznych narzędzia, warunków skrawania i właściwości obrabianego materiału. W nie uwzględniono wpływu ścina wiertła.
